On a slow day a few years ago I was looking at some US West (now
Qwest) tariffs at the Oregon PUC. Most of the documents had wording
that went something like "...Pacifc Northwest Bell, dba US West...",
with dba standing for "doing business as". I don't know this for
sure, but I'm guessing changing the name of a big company might be
really expensive but using another name for the business might be as
easy as filing a form with a state's corporation commission. This
same syndrome afflicts many railroads; One road buys another, paints
new logos all over everything but retains the old name on deeds to
properties, operating authorities and the like. In addition to being
expensive this tactic might shield the new owner from misdeeds of the
former company. Who knows?
